Antarctica still not warming

Do you believe that the South Pole is warming and that the Antarctic ice cap is melting? Just about everybody does. But as is often the case with global warming, the truth is quite different than what is reported. Numerous peer-reviewed papers have shown that the Antarctic is cooling and gaining ice mass. The most recent study to look at Antarctic temperature trends is published in the Journal of Geophysical Research (abstract can be read here).

The researchers found a statistically insignificant positive trend in Antarctic temperatures during the period 1960-2005. They found a weak negative trend from 1970 to 2005. Finally, they found a widespread, but again, statistically insignificant warming trend from 1992 to 2005. In other words, there's a whole lot of nothin' going on at the South Pole.
